The free energy plays a fundamental role in theories of phase transformations and
microstructure evolution. It encodes the thermodynamic coupling between different fields …

The influence of pre-strain and temperature on the superior properties exhibited by an Nb
nanowire embedded in a NiTi shape memory alloy (SMA) are investigated via molecular …

Ni 4 Ti 3 precipitates, which generally exist in aged Ni-rich NiTi shape memory alloys
(SMAs), can have a profound effect on material properties. However, the fundamental …

NiTi shape memory alloys are promising elastocaloric materials owing to their substantial
adiabatic temperature change (ΔT ad). However, the simultaneous attainment of large ΔT ad …

As a diffusionless phase transformation, martensite evolves at the speed close to sound,
with its kinetics and morphology dominated by the mechanical energy. However, the …
